4 Claims.

The object of our invention has been to provide a self-sharpening safety razor which is another species of the genus that is the subject of our application for patent executed of even date herewith, Ser. No. 676,626 for a self-sharpening safety razor.

While we are illustrating the said species by the best embodiment thereof known to us, our invention is not to be limited to the said embodiment herein shown, but it is to be understood that changes may be made therein, without necessary departure from the principles herein involved.

In the accompanying drawings:

Figs. 1 and 2 are respectively side and back elevations.

Figs. 3 and 4 are respectively a plan view and a front elevation of the said razor, embodying our invention, said razor having a blade thereon, and the blade being in position for shaving.

Fig. 5 is a plan view of said razor with the blade removed.

Figs. 6 and 7 are respectively vertical cross sections of the lines A-A and BB of Fig. 4, the full' lines showing the parts in position for shaving, and the dotted lines in Fig. 7 showing the position of the guard plate and hone plate at the outer end of the sharpening movement.

Figs. 8 and 9 are respectively a plan and an edge view of the form of our razor blade shown in Figs. 1, 2, 3, 6 and 7.

In the following particulars our razor which is the subject of this application, is or may be like the razor which is the subject of the aforesaid application for patent:

Essentially our razor comprises a handle l0 carrying a head ll, said razor having means for so supporting a guard plate l2 having a hone plate Ila secured thereto, that they may be reciprocated transversely to the cutting edge iii of the razor blade I4, so as to sharpen the razor edge. In the present instance, the razor blade is clamped between the two jaws it of a yoke l1, and the said yoke I1, rests in theangle between preferably vertical shoulder I8 formed on a wall Ilia on the head ll, and seats H3 at the foot of said shoulder, which seats preferably slope downward in a direction toward the cutting edge of the razor.

The razor blade, in the present instance, is held against the said shoulder l8 and down upon the seats l9 and the blade is held down upon the hone plate 12a, by a spring 20, which, in the.

illustrated embodiment, has trunnions 2| that are engaged in holes formed in the ends of the said yoke, and has a latch section 22 which is adapted to be sprung under a shoulder 23 that is formed on the said head, preferablyat a level below the seats I9 and at a point sufficiently to the rear of the trunnions 2| so that forcing the said latch section 22 beneath the said shoulder 23 will pull the said yoke firmly against the said wall l8 and will also pull it down upon the seats I 9 and furthermore, that will yieldingly pull the blade down upon the hone plate.

The present invention relates to the manner of supporting the guard and honeplate and of effectuating their reciprocation back and forth under the cutting edge of the blade for the purpose of sharpening. A guide pin 25 is secured to a lug or ear 26 depending from the guard plate and is slidably mounted in a bore 21 formed in the head of the razor. Thus, the shaking of the razor will cause the guard and hone plate to be reciprocated back and forth under the razor edge, the movement being guided by the said pin 25. The extent of movement of the said plates away from the said head is limited by the engagement of lugs" 28 depending from the rear edge of the plate with shoulders 29 formed on the head beneath the front portion of the guard plate as shown in Figs. 1, 4, 5, 6, 7.

The parts are so related that there is a space 30 between the guard plate and the portion of the head immediately beneath, so that the guard plate may rock or tilt on the pin 25, to permit the hone plate to accommodate itself to the cutting edge of the blade so as to contact with it throughout its length.

In operation, it is only necessary, in order to eifectuate sharpening of the blade, that the razor be shaken; and the guard and hone plate will reciprocate back and forth under said edge and accomplish the desired result, the spring 20 yieldingly pressing the blade upon the bone plate during the operation.

The aforesaid invention which is the subject of this application afio-rds a self-sharpening razor of extreme simplicity, both in construction and in manipulation, a space being provided beneath said guard so that said guard and hone plate may tilt about the axis of said cylindrical guide to properly contact with the cutting edge of the blade, a lug on said plates, and a stop on said head for limitingthe forward movement of the guard and hone plate.

What we claim is:

l. A safety razor comprising a handle, a head having a seat for a razor blade, a combined guard and hone plate, and a slide mounted in said head parallel to and supporting said plates, said slide comprising a cylindrical guide.

2. A safety razor comprising a handle, a head having a seat for a razor blade, a combined guard and hone plate, a slide mounted in said head parallel to and supporting said plates, said slide comprising a cylindrical guide, a space being provided beneath said guard, so that said guard and hone plate may tilt about the axis of said cylindrical guide to properly contact with the cutting edge of the blade.

3. A safety razor comprising a handle, a head having a seat for a razor blade, a combined guard and hone plate, a slide mounted in said head parallel to and supporting said plates, said slide comprising a cylindrical guide, 2. lug on said plates, and a stop on said head for limiting the forward movement of the guard and hone plate.

4. A safety razor comprising a handle, a head having a seat for a razor blade, a combined guard and hone plate, a slide mounted in said head parallel to and supporting said plates, a cylindrical guide and a lug on said slide, and a shoulder on said head for limiting the backward movement of said guard and hone plate by limiting the backward movement of said lug.
